SUPPORT FOR THE GUN-CARRIAGES RAILWAY -GUNS 0N TURNTABLES.

Specification of Letters Patent.

Application filed September 4, 1920. Serial No. 408,380.

T 0 all whom it may concern Be it known that I, FRITZ F INoKH, residing at Essen, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Supports for the Gun-Carriages of Railway-Guns on Turntables, of which the following is a specification. V

The object of the invention is to provide supporting means for the gun carriage mountings of railway guns upon a turntable, which render it possible to prepare the gun, which is mounted on the turntable, rapidly ready for firing.

The invention will be described with reference to the accompanying drawings in which- Figure 1 shows the turn-table and the gun carriage, partly in section and partly in side elevation,

Fig. 2 the plan view of Fig. 1,

Fig. 3 a section 3-3 of Flg. 2 and Figs. t6 correspond to Figs 1-3, with the turn-table and the gun in their firing position.

The turn-table bridge A supported on ball bearings a on a track B comprises a pair of girders (E, a intersecting each other at right c ngles, between which girders a rails C are laid, which in the position of the turn table ready for receiving the carriage, form a continuation of the rails C which lead to the turn-table. The reciprocal distance of the girders a is so chosen, that the normal clearance gage of the railway, shown in Fig. 3 with dotted lines, is maintained. The distance between the turntable supports a is less; and corresponds to thedistance between the main supports D of the gun carriage. The carriage rests upon two bogies D and D The cradle E which carries the gun barrel E is fixed to the main girders of the carriage by means of horizontal trunnions e in such a way that, when fired at its highest elevation, the breech end of the gun extends at the end of the recoil to beneath the upper edge of the rails C (see the position of the recoil marked by dotted lines in Fig. 4). The breech end of the gun barrel then enters a gap at in the turntable (Figs. 25). In the case of heavy guns the breech end of the gun barrel is wider than the free. space between the rails.

When the turn-table is in the position shown in Figs. 1-3 the gun is mounted on it in such a way that the trunnions are situated practically over the 'middle of the turn-table. The bogies D D then rest on the rails C on both sides of the gap in the turn-table. The turn-table is then swung at an angle of 90 in the direction of the arrow at (Fig. 2) into the position shown in Figs. e f-6, so that the girders a of the turn-table come under the supports D of the gun carriage. Then after the gun carriage has been lifted off them by means of lifting jacks or the like the bogies D D are moved to the side and then the gun carriage is lowered, so that its supports D rest on the turn-table supports 00*.

The turning of the turn-table from the receiving position to the firing position has the advantage that thegun carriage can be placed directly on to the turn-table supports a it is, therefore not necessary to attach beams or wedges for supporting the gun carriage to the turn-table supports a on which, owing to their distance apart, the

gun carriage could only rest indirectly.

Further, by turning the turntable the rails C are moved in the simplest manner out of the way of the recoiling breech end of the gun barrel. By this means the tedious removing of the rails C and their supports is avoided, so that for this reason the gun, when mounted on the turn-table, is very rapidly ready for firing.

laims:

1. A device of the class described which comprises a turntable, a pair of girders forming a part of the turntable, a line of rails carried by said turntable and between said pair of girders, a second pair of girders disposed transversely of said line of rails, an opening between said second pair of girders, said line of rails enabling a gun carriage of railway guns to be positioned over said turntable.

2. A device of the class described which comprises a turntable, a line of tracks on said turntable, a pair of supporting members mounted on said turntable and transversely of said line of tracks, all of which are so arranged that a railway gun may be i run across said turntable and thereafter the gun mounted on said supporting members.

3. A device of the class described comprising a turntable, a line of rails carried by said turntable, two pair of main girders forming a part of said turntable, one pair of said girders being disposed at right angles to the line of rails, said line of rails enabling a gun carriage of railway guns to be positioned over sald turntable, the distance between said transversely disposed girders being the same as the distance between the main supports of the gun carriage, whereby the turntable may be rotated to position the transversely dis osed girder 10 under the main supports of t e'gun carriage, substantially as and for the purpose set forth.
